Abstract
Roll bending or roll forming is one of the metal forming processes used in manufacturing industries. Various products having cylindrical, conical or elliptical profiles are manufactured using roller bending process. Trial and error method is generally used to achieve desired curvature or shape of final products. Prediction of top roller displacement of three-roller bending machine in downward direction to obtain desired radius of curvature is utmost concern. A generalized mathematical model is developed using dimensional analysis. Dimensional analysis is simplest tool for mathematical modeling when relationship among variables is unknown. Dimensional analysis is used to make the independent and dependent variables dimensionless and to get dimensionless equation. Multiple regression analysis is applied to this dimensionless equation to obtain the index values based on the least square method. Developed model is validated with experimental data and root mean square error between computed and estimated values are calculated.
